为充分利用高铁非高峰期的列车运能,高铁快运已成为铁路快捷货运发展新趋势.然而,受客运需求波动影响,载客动车组可用于高铁快递的运能呈现高度不确定性,给日常运营组织带来巨大挑战.为增强高铁快运系统应对随机运能的能力,提出一种考虑随机运能的高铁快递运输计划优化方法.首先,采用离散场景刻画列车运能的不确定性,以最大化高铁快运期望总收益为目标,综合考虑快递的送到时限和运营约束,针对场景概率分布精确已知情形,构建两阶段随机规划模型(SP);然后,进一步考虑场景概率分布信息部分已知情形,构建两阶段分布鲁棒优化模型(DRO),基于盒式模糊集,借助对偶理论将DRO模型转化为等价的整数线性规划模型并利用GUROBI求解;最后,基于宁杭高铁设计数值实验验证模型的有效性,结果表明,相较于SP模型,DRO模型体现出较强的鲁棒性,只需付出较小的代价即可有效抵抗运能波动对运输计划的影响,并且能够改善最坏情形下解的质量,切实改善高铁快递实际运营中的稳定性.

基于1988—2018年中国家庭收入调查数据,以城乡基本医疗保险制度实施为准自然实验,采用双重差分法考察了城镇基本医疗保险与新型农村合作医疗保险(即新农合)对家庭消费率的影响及其机制。结果显示:相较于未参保家庭,参加城镇医保的家庭消费率显著高出1.01%,但新农合的影响不显著;机制分析发现,城镇医保促进了参保家庭的总消费和分项消费支出,但新农合对消费支出无显著影响,同时,城镇医保和新农合对总收入和大部分分项收入无显著影响,这与基准回归结果一致;异质性分析表明,城镇医保更多地提升了中老年、非富裕、不健康群体,以及西部地区的家庭消费率。对此,应当充分发挥基本医疗保险制度对提振家庭消费率的积极作用,对“大水漫灌”式的财政补助应进行反思;改变基本医保“户保分离”“业保分离”的现状;加强针对特定人群的医保政策;注重提高参保青年和健康群体的获得感。

The programmable CRISPR-Cas genome editing technology,adopted from prokaryotic adaptive immune systems,has revolutionized genome engineering in plants(Liu et al.,2022a).Many efforts have been made to improve the activity,specificity,and protospacer adjacent motif(PAM)variants of Class 2 Cas nucleases,such as Cas9,Cas12a,and Cas12b(Liu et al.,2022a).However,their large size(∼1000–1400 amino acids)poses a challenge in scenarios requiring a compact Cas nuclease,particularly in urgent situations like plant virus-induced genome editing(Cheuk and Houde,2018;Li et al.,2021;Varanda et al.,2021).
